Fused filament fabrication has found its genius little sister in the form of laser metal deposition. The process builds parts layer after layer using the heat of an integrated blue laser. This allows Melanie Lang and FormAlloy to use a shorter wavelength than IR lasers which then allows for a wider range of material processing. Their blow powder system and modular powder feeders allows them to use different materials on the fly. With this technology that was inspired by aerospace engineering needs, they build parts that have complex geometric structures without any support material in deposition 3D printing.
